A practical nurse is preparing to provide oral hygiene to a client who is comatose following a traumatic brain injury. Arrange the following actions in the order the nurse should perform them to ensure client safety and comfort. All options must be used.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to first position the client laterally, then place the towel and basin, insert the padded tongue blade, cleanse the mouth while suctioning, and finally apply lip lubricant.
When providing oral hygiene to an unconscious or comatose client, the greatest risk is aspiration of fluids or secretions into the lungs because the client lacks an intact swallowing and gag reflex. Therefore, the nurse must first turn the client to a lateral (side-lying) position so that fluids naturally drain out of the mouth. Once the airway is protected, the nurse prepares the area with a towel and basin. A padded tongue blade is then used to safely keep the mouth open without risking injury. The nurse cleans the mouth while immediately suctioning any fluids to further prevent aspiration. Finally, water-soluble lubricant is applied to protect the lips from drying and cracking.

Adım Adım Çözüm

1
Determine the highest priority action based on the client's neurological status.
Positioning the client in a lateral (side-lying) position is identified as the first and most critical step.
A comatose client lacks an intact gag reflex. Airway protection is the absolute priority; the lateral position allows fluids to drain out of the mouth by gravity, preventing aspiration.
2
Identify the preparatory steps for the procedure.
Placing a towel and emesis basin is identified as the second step.
After the client is in a safe position, the nurse protects the client's gown and bed linens from secretions and cleaning solutions.
3
Determine the safest method to access the oral cavity.
Inserting a padded tongue blade is selected as the third step.
Unconscious clients may reflexively bite down. The nurse must never insert fingers into the client's mouth. A padded tongue blade safely keeps the mouth open for cleaning.
4
Sequence the core intervention of oral care.
Cleansing the oral cavity while actively suctioning is identified as the fourth step.
Once the mouth is safely open, the nurse cleans the teeth and gums. Continuous or frequent suctioning is required to remove introduced fluids and loosened secretions.
5
Identify the final comfort measure.
Applying a water-soluble lubricant to the lips is the final step.
After the oral cavity is cleaned and secretions are removed, applying lubricant prevents drying, cracking, and potential tissue breakdown of the lips.

Cevap

The correct sequence for doffing PPE is to first remove the gloves, then the face shield, followed by the isolation gown. After these items are removed, the nurse must exit the room and close the door before finally removing the N95 respirator.
According to standardized CDC guidelines for doffing personal protective equipment (PPE), the most contaminated items must be removed first to prevent cross-contamination. Gloves are removed first, followed by the face shield or goggles (handled by the clean ear pieces or headbands). Next, the isolation gown is removed by unfastening the ties and rolling it inside out. When Airborne Precautions are in place, the nurse must then exit the isolation room and close the door before safely removing the N95 respirator in the hallway or anteroom.

Adım Adım Çözüm

1
Identify and remove the most contaminated piece of equipment first.
The gloves are removed and discarded in the appropriate receptacle.
This prevents the transfer of pathogens from the hands to the face or hair during the removal of other PPE.
2
Remove face and eye protection.
The face shield is removed by handling only the clean headbands or ear pieces.
The front of the face shield is considered contaminated; handling only the back straps prevents hand contamination.
3
Remove the remaining body coverage.
The isolation gown is unfastened and rolled inside out into a bundle.
Rolling the gown inside out contains the MRSA pathogens present on the front and sleeves.
4
Maintain airborne protection while in the infectious environment.
The nurse exits the room and ensures the door is closed.
The N95 respirator must remain on while inside the airborne infection isolation room to filter aerosolized tuberculosis bacteria.
5
Remove respiratory protection in a safe area.
The N95 respirator is removed strictly outside the room and discarded.
This ensures the nurse is in a clean environment before exposing their respiratory tract to ambient air.

A practical nurse is preparing to transfer a client who has left-sided hemiparesis following a cerebrovascular accident from the bed to a wheelchair. In what order should the nurse perform the following actions? (Move the steps into the correct chronological order.)

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence is: Position the wheelchair on the right side and lock wheels, assist to a sitting position on the edge of the bed, secure the transfer belt, brace the left knee, and finally assist to stand and pivot on the right leg.
Safe transfer of a client with hemiparesis requires strict adherence to biomechanical principles. The environment must be prepared first by placing the wheelchair on the strong (right) side to ensure the client pivots toward their strength. The client is then brought to a sitting position to stabilize blood pressure. A transfer belt is applied next for a secure hold. Before standing, the nurse must brace the weak (left) knee to prevent it from collapsing. Finally, the client uses their strong side to pivot and stabilize themselves in the wheelchair.

Adım Adım Çözüm

1
Determine the client's strong and weak sides based on the diagnosis of left-sided hemiparesis.
The left side is weak, and the right side is strong.
Transfers must always be initiated toward the client's strong side for safety and stability.
2
Place the equipment (wheelchair) in the optimal position.
The wheelchair is placed on the right side at a 45-degree angle and locked.
Equipment must be ready and secure before moving the client.
3
Prepare the client physically for the transfer.
The client is assisted to a dangling position with feet flat, and the transfer belt is applied.
Dangling prevents orthostatic hypotension, and flat feet provide a solid base. The belt ensures a safe grip for the nurse.
4
Position yourself to protect the client's weak extremities.
The nurse faces the client and braces the left knee.
Hemiparetic extremities can buckle easily under weight; bracing provides external support.
5
Execute the pivot transfer.
The client pivots on the strong right leg and reaches with the strong right hand.
Pivoting on the strong side allows the client to bear their own weight safely and control their descent into the chair.

Cevap

The correct priority sequence is to first call for assistance while staying with the client, then position the client to reduce abdominal tension, cover the exposed organs with moist sterile dressings, obtain vital signs to assess for shock, and finally prepare the client for emergency surgery.
Wound evisceration is an acute medical emergency requiring immediate, stepwise intervention. First, the nurse must call for help while remaining at the bedside to ensure safety and escalate care. Second, placing the client in a low Fowler's position with knees flexed minimizes intra-abdominal pressure and halts further organ protrusion. Third, applying sterile, saline-soaked dressings protects the exposed bowel from ischemia and necrosis. Fourth, monitoring vital signs assesses the client for hemodynamic instability and shock. Finally, ensuring NPO status and preparing the client for surgery addresses the definitive medical treatment.

Adım Adım Çözüm

1
Call for immediate assistance while remaining with the client.
Help is summoned without abandoning the unstable client.
Evisceration is a life-threatening surgical emergency requiring a provider and an operating room. The PN must stay with the client to prevent further injury while help is dispatched.
2
Position the client in a low Fowler's position with the knees flexed.
Abdominal muscle tension is minimized.
This specific position relieves pressure on the abdominal cavity, physically preventing further protrusion of the intestines.
3
Cover the protruding bowel with sterile dressings moistened with sterile normal saline.
The exposed bowel is protected from drying and infection.
Exposed internal organs can quickly become ischemic or necrotic if allowed to dry out. A moist, sterile environment preserves tissue viability.
4
Obtain a complete set of vital signs to monitor for signs of shock.
Baseline hemodynamic status is established during the emergency.
The client is at high risk for hypovolemic shock due to fluid shifts and trauma. Vital signs dictate further circulatory interventions.
5
Ensure the client is on strict nothing by mouth (NPO) status and prepare for emergency surgery.
The client is readied for surgical repair.
The definitive treatment for an evisceration is surgical closure. Ensuring NPO status prevents aspiration during the impending administration of anesthesia.

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to first withhold the medications, then assess the client's apical pulse, report the findings to the registered nurse, and finally document the actions taken.
When a practical nurse identifies a critical laboratory value such as a potassium level of 2.62.6 mEq/L, the immediate priority is client safety. The PN must first withhold any medications that could exacerbate the condition, such as furosemide (which wastes potassium) and digoxin (which becomes highly toxic in hypokalemia). Next, the PN must assess the client for active complications, specifically checking the apical pulse for arrhythmias. Once the assessment data is collected, the PN reports a complete clinical picture to the RN to facilitate prompt medical intervention. Finally, all findings and actions are thoroughly documented in the electronic health record.

Adım Adım Çözüm

1
Withhold the administration of the scheduled digoxin and furosemide.
Further depletion of potassium and potential digoxin toxicity are prevented.
Safety is the initial priority. Furosemide actively depletes potassium, and hypokalemia severely increases the risk of life-threatening digoxin toxicity.
2
Assess the client's apical pulse and observe for signs of profound muscle weakness.
Current clinical data regarding the client's physiological response to hypokalemia is obtained.
The PN must determine if the critical lab value is actively causing adverse effects, such as cardiac arrhythmias, before notifying the healthcare team.
3
Report the critical potassium level and the client's vital signs to the supervising registered nurse.
The registered nurse and healthcare provider are alerted to the emergency.
Escalation is required so the provider can prescribe corrective treatments, such as potassium replacement therapy.
4
Document the withheld medications, assessment findings, and the RN notification in the health record.
A clear, legal record of the clinical event and nursing interventions is created.
Documentation should occur after the client is stabilized and the healthcare team has been notified of the critical findings.

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to first position the client side-lying, place protective linens and a basin, safely open the mouth with a padded tongue blade, perform the cleaning with simultaneous suctioning, and finally moisturize the lips.
When providing oral hygiene to an unresponsive client, safety—specifically airway protection—is the absolute highest priority. Therefore, the client must first be turned to a side-lying position to utilize gravity for drainage. Once positioned safely, the nurse prepares the area with a towel and basin to maintain cleanliness. Next, safe access to the oral cavity is secured using a padded tongue blade, preventing injury from reflex biting. The actual cleaning is then performed simultaneously with suctioning to ensure no fluid accumulates in the airway. Finally, the procedure concludes with a comfort measure, applying water-soluble lubricant to prevent the lips from drying and cracking.

Adım Adım Çözüm

1
Assist the client into a side-lying position.
The client is in a safe posture for oral care.
The side-lying position allows fluids to pool in the side of the mouth and drain out, significantly reducing the risk of aspiration.
2
Place a towel under the client's chin and an emesis basin against the cheek.
The physical environment is prepared.
This step protects the client's gown and linens from becoming soiled and provides a receptacle for the oral drainage.
3
Insert a padded tongue blade gently between the back molars to open the mouth.
The oral cavity is safely accessed.
An unresponsive client may bite down reflexively. Using a padded tongue blade protects both the client's teeth and the nurse's fingers.
4
Clean the teeth and oral mucosa using a moistened swab while applying suction.
The mouth is cleaned and secretions are removed.
Cleaning removes plaque and bacteria. Continuous or intermittent suctioning ensures that the fluid used for cleaning and any loosened secretions are not aspirated into the lungs.
5
Apply a water-soluble lubricant to the client's lips.
The client's lips are protected from cracking.
Unresponsive clients often breathe through their mouths, leading to dry lips. A water-soluble lubricant maintains tissue integrity without the flammability risk associated with petroleum-based products.

Cevap

The correct sequence for managing a suspected central line air embolism is to first clamp the catheter to stop air entry, then position the client in a left lateral Trendelenburg position to trap the air, followed by administering high-flow oxygen, activating the Rapid Response Team, and finally obtaining vital signs.
The sequence reflects the fundamental principles of risk reduction during an acute central line complication: stop the source of the injury (clamp), mitigate the immediate pathophysiological risk (position to trap air), treat the physiological symptoms (oxygen), escalate care (call for help), and evaluate the client's status (vital signs).

Adım Adım Çözüm

1
Clamp the disconnected central venous catheter.
Stops further air from entering the circulatory system.
The most critical initial action in any mechanical hazard is to eliminate the source of the harm before addressing the consequences.
2
Place the client in a left lateral Trendelenburg position.
Traps the air embolus in the right ventricle.
This specific gravitational positioning prevents the air bubble from moving forward into the pulmonary circulation, which would cause an acute right ventricular outflow obstruction.
3
Administer high-flow oxygen.
Treats systemic hypoxia and reduces the size of the embolus.
Administering 100% oxygen addresses the respiratory distress and creates a diffusion gradient that helps the body resorb the nitrogen-rich air bubble.
4
Activate the Rapid Response Team.
Summons advanced medical and critical care support.
An air embolism is a profound systemic emergency requiring interventions and continuous monitoring beyond the practical nurse's scope of practice.
5
Obtain vital signs.
Establishes a baseline of the client's current physiological status.
Vital signs provide essential, objective data regarding cardiac output and respiratory effort for the Rapid Response Team upon their arrival.

Cevap

The correct sequence is to first change the drawing-up needle, then retract the skin and subcutaneous tissue, insert the needle at a 90-degree angle, inject the medication while pausing for 10 seconds, and finally withdraw the needle while simultaneously releasing the skin.
The Z-track method requires strict adherence to a specific sequence to prevent tissue damage. First, a new needle must be attached to ensure the outside is free of irritating medication. Next, the skin is retracted to displace the tissue layers. The needle is then inserted at 90 degrees. After injecting slowly, a 10-second pause is necessary for medication dispersion. Finally, withdrawing the needle and releasing the skin simultaneously seals the track, trapping the medication in the muscle.

Adım Adım Çözüm

1
Change the drawing-up needle to a new, sterile administration needle.
Ensures the exterior of the needle shaft is free of medication.
Iron dextran can cause permanent tissue staining and severe irritation if deposited in the subcutaneous layers during insertion.
2
Retract the skin and subcutaneous tissue 1 to 1.5 inches laterally.
Moves the superficial tissues out of alignment with the underlying muscle.
This is the core principle of the Z-track method, preparing the 'zigzag' path that will lock the medication in the muscle.
3
Insert the needle at a 90-degree angle.
Penetrates through the displaced tissue directly into the muscle belly.
A 90-degree angle is required for intramuscular injections to ensure the medication reaches deep muscle tissue.
4
Inject the medication slowly and maintain the needle's position for 10 seconds.
Deposits the medication and allows it to begin diffusing into the surrounding muscle fibers.
Slow injection minimizes discomfort, and the 10-second pause prevents the medication from immediately welling up the injection track.
5
Withdraw the needle and release the retracted skin simultaneously.
The tissue layers slide back into their original positions, breaking the needle track alignment.
This seals the track, effectively trapping the irritating medication deep within the muscle and preventing seepage to the surface.

Anahtar Kavram

The Z-track method for intramuscular injections is used to prevent highly irritating or staining medications from leaking back into the subcutaneous tissue by displacing tissue layers before injection.

Cevabı ve açıklamayı göster

Cevap

The correct sequence for removing PPE is: 1) Gloves, 2) Face shield, 3) Gown, 4) Surgical mask, and 5) Hand hygiene.
According to the Centers for Disease Control and Prevention (CDC) guidelines, the safest standard sequence for removing PPE individually is to remove gloves first, followed by the face shield or goggles, then the gown, and finally the mask or respirator, concluding with thorough hand hygiene. This specific order ensures that the most heavily contaminated items (gloves and gown front) are removed in a way that minimizes the risk of transferring pathogens to the nurse's face, mucous membranes, or clean uniform.

Adım Adım Çözüm

1
Determine the most contaminated item of PPE to remove first.
Gloves are identified as the most heavily contaminated item from direct patient and environmental contact and are removed first.
Removing the most contaminated item initially minimizes the immediate risk of cross-contamination to the nurse's face, hair, and uniform during subsequent steps.
2
Identify the next item to remove that protects the face but can be handled by clean straps.
The face shield is removed next by handling only the clean earpieces or headband at the back of the head.
This protects the mucous membranes of the eyes and is safely removed before the gown to prevent contaminated gown particles from reaching the face.
3
Remove the core body protection.
The gown is unfastened, pulled away from the neck and shoulders, and rolled inside out.
Rolling the gown inside out traps the surface contaminants within the bundle, preventing them from brushing against the nurse's clean uniform.
4
Remove the respiratory protection.
The surgical mask is removed by untying the bottom strings, followed by the top strings, touching only the ties.
The mask is kept on until the end to protect the respiratory tract from any aerosolized particles that might be generated while taking off the gown and other PPE.
5

Cevabı ve açıklamayı göster

Cevap

The correct sequence is: perform hand hygiene and don gloves, remove the old patch, clean the new application site, label the new patch, and apply the new patch to a rotated site.
Safe application of a transdermal patch requires a systematic approach to protect both the nurse and the client. First, the nurse must don gloves to avoid self-absorption of the vasoactive medication. Second, the old patch must be removed to prevent an accidental overdose. Third, the new site is cleaned with water to promote adherence. Fourth, the patch is labeled before application to prevent pressing too hard on the client's skin. Finally, it is applied to a new, hairless area to prevent contact dermatitis and ensure consistent medication absorption.

Adım Adım Çözüm

1
Perform hand hygiene and put on clean gloves.
Prevents nurse exposure.
Nitroglycerin can be easily absorbed through the nurse's skin, potentially causing a severe headache or hypotension.
2
Remove the previous patch and fold it in half with the adhesive sides together.
Discards old medication safely.
Leaving the old patch on while applying a new one can cause a dangerous medication overdose.
3
Cleanse the new application site with water and allow it to dry completely.
Prepares a clean surface.
Ensures the new patch adheres properly and absorbs at a predictable, steady rate.
4
Write the date, time, and initials on the outside of the new patch.
Documents the administration.
Facilitates tracking for the next nurse and avoids pressing a writing instrument into the client's tissue.
5
Apply the new patch to a rotated, hairless area of intact skin.
Administers the medication.
Site rotation minimizes local skin irritation and maintains optimal skin integrity for future applications.

Anahtar Kavram

Cevap

The correct sequence for doffing PPE in this scenario is: remove gloves, remove gown, perform hand hygiene and exit the room, remove the N95 respirator outside the room, and perform a final hand hygiene.
The Centers for Disease Control and Prevention (CDC) guidelines for removing PPE require the most contaminated items to be removed first. Gloves are removed initially, followed by the gown. Because the client requires airborne precautions, the N95 respirator must remain on until the nurse has exited the room and closed the door. Hand hygiene is essential both before exiting the room (to avoid contaminating the door handle) and after removing the respirator.

Adım Adım Çözüm

1
Remove gloves
Gloves are safely discarded in the room.
Gloves are the most contaminated item and are removed first to prevent transfer of pathogens to the body or environment.
2
Remove the isolation gown
Gown is rolled inside out and discarded in the room.
The front and sleeves of the gown are contaminated. Removing it inside the room prevents spreading contact pathogens into the hallway.
3
Perform hand hygiene and exit the room
Hands are clean before touching the door.
This prevents contaminating the doorknob and the environment outside the isolation room.
4
Remove the N95 respirator outside the room
Respirator is safely removed and discarded.
Airborne pathogens can remain suspended in the air. The respirator must stay in place until the nurse is completely outside the contaminated airspace.
5
Perform final hand hygiene
Hands are completely sanitized.
Touching the straps of the respirator during removal may transfer small amounts of pathogens to the hands.

A practical nurse (PN) is inserting a nasogastric (NG) tube for a client with a bowel obstruction. To reduce the risk of respiratory trauma and aspiration, arrange the following procedural steps in the correct chronological order.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence for safe nasogastric tube insertion is to first measure the required tube length, then hyperextend the client's neck for initial nasal insertion, flex the chin to the chest once the tube reaches the throat, advance the tube while the client swallows, and finally verify placement by aspirating and testing the pH.
The correct sequence ensures client safety by aligning the airway anatomy appropriately at each stage of the procedure. Measurement must occur first to identify the target depth. The head is tilted back initially only to facilitate nasal entry. Crucially, the head must be tilted forward (chin-to-chest) when the tube reaches the back of the throat to close the trachea. Swallowing assists esophageal passage, and verifying placement via pH is the final bedside safety check before utilizing the tube.

Adım Adım Çözüm

1
Determine the proper insertion depth.
The PN measures from the nose to the earlobe down to the xiphoid process.
This establishes a reliable landmark to ensure the tube reaches the stomach without coiling in the esophagus.
2
Navigate the nasal cavity.
The client hyperextends their neck while the PN advances the tube.
Tilting the head back straightens the nasal passage, minimizing mucosal trauma during initial entry.
3
Protect the airway at the oropharynx.
The client flexes their chin toward their chest.
This anatomical shift forces the epiglottis to cover the glottis, which is vital for preventing the tube from entering the trachea.
4
Pass the tube down the esophagus.
The client swallows water as the PN advances the tube.
Swallowing initiates peristalsis and keeps the airway closed, facilitating a smooth and safe passage into the stomach.
5
Verify initial placement.
The PN aspirates contents and checks the pH.
Testing the pH of the aspirate confirms acidic gastric placement, immediately reducing the risk of inadvertently administering fluids into the lungs.

Anahtar Kavram

Correct anatomical positioning—specifically transitioning from neck hyperextension to chin-to-chest flexion—during nasogastric tube insertion is a critical maneuver to close the airway and prevent accidental tracheal intubation.

A practical nurse is preparing to transfer a client who has left-sided weakness from the bed to a wheelchair. In what order should the nurse perform the following actions? Arrange the steps in the correct sequence from first to last.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence is: position the wheelchair on the strong side, lock the brakes, assist the client to a sitting position, apply the transfer belt, and finally assist the client to stand and pivot.
The correct sequence prioritizes environmental preparation, equipment safety, client physiological readiness, the application of safety devices, and finally, the execution of the transfer using proper body mechanics.

Adım Adım Çözüm

1
Position the wheelchair on the client's strong side (right side) at a 45-degree angle.
The wheelchair is optimally aligned for the safest possible transfer.
Transferring toward the strong side allows the client to bear weight and use their unaffected limbs for support during the pivot.
2
Lock the brakes on the bed and wheelchair.
Both surfaces are completely immobilized.
This prevents the equipment from sliding away during the weight shift, significantly reducing the risk of a fall.
3
Assist the client to sit on the edge of the bed with their feet flat on the floor.
The client is upright and stabilized with a solid base of support.
Dangling allows the body to adjust to the position change, preventing dizziness from orthostatic hypotension before standing.
4
Apply a transfer belt snugly around the client's waist.
The nurse has a secure, mechanical grip point.
A gait belt decreases the risk of dropping the client and prevents injury to the nurse's back or the client's limbs by avoiding lifting under the arms.
5
Brace the weak leg, assist the client to stand, and pivot.
The client is safely moved from the bed into the wheelchair.
Bracing the hemiparetic left leg prevents the knee from collapsing under the client's body weight, ensuring a controlled descent into the chair.

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to roll the NPH vial, inject air into the NPH vial, inject air into the regular insulin vial, withdraw the regular insulin, and finally withdraw the NPH insulin.
The correct sequence for mixing insulins ensures precise dosing and prevents contamination of the vials. The PN must first gently roll the NPH (cloudy) insulin to resuspend the particles. To prevent negative pressure, air is injected into the NPH vial first, followed by injecting air into the regular (clear) insulin vial. The regular insulin is drawn up immediately after injecting air into its vial (clear before cloudy). Finally, the NPH insulin is drawn up. This sequence prevents the intermediate-acting NPH insulin from accidentally entering and altering the pharmacokinetics of the rapid/short-acting regular insulin vial.

Adım Adım Çözüm

1
Roll the NPH insulin vial gently between the palms.
The NPH insulin suspension is evenly mixed without creating air bubbles.
NPH insulin is a suspension that settles on standing and requires gentle mixing prior to use to ensure accurate dosing.
2
Inject air equal to the prescribed dose into the NPH insulin vial.
The NPH vial is pressurized.
Prevents negative pressure in the vial. Doing this first keeps the needle free of regular insulin, preventing contamination of the NPH vial.
3
Inject air equal to the prescribed dose into the regular insulin vial.
The regular insulin vial is pressurized and ready for withdrawal.
Prevents negative pressure. Because the needle is now in the regular insulin vial, withdrawal can begin immediately without removing the needle.
4
Withdraw the prescribed dose of regular insulin into the syringe.
Clear insulin is drawn into the syringe.
Regular (clear) insulin is always drawn up first. This prevents contamination of the rapid-acting insulin vial with the longer-acting NPH insulin.
5
Withdraw the prescribed dose of NPH insulin into the syringe.
The mixed dose is completed accurately.
NPH (cloudy) insulin is drawn last because introducing regular insulin into the NPH vial does not negatively alter the intermediate-acting insulin's properties.
